About the watch, or bracelet - I am pretty sure I remember that during the early searches, people were being specifically asked to cover the ground inch by inch looking for jewelry- which leads me to believe that they haven't recovered the object from her wrist.
About the Lie detector result - we were told that one POI had passed. I have a strong feeling it is JR- but we have never been told who that person was. Now that is strange, because all these kids are "lawyered up" and usually the lawyer for the one who passed would be getting that info about his client out there in the public. It could be that that POI or his family is being extremely reticent to be mentioned at all in the press, but I don't think so. I think it is possible that LE does not want the rest of the POI's to know who it is so they have requested that the POI and his lawyer refrain from making their IDs public.
The reason I believe that it may be JR who passed is that if it were, then the primary suspect would have a good idea that he is indeed the primary suspect. I don't think it would matter if any of the others passed, and then we would have been told who it was.
I believe there really are only a few possibilities here - JR or JW, alone, or together, or either one with another unnamed associated POI. Either that, or a stranger.
Honestly, I have such a hard time believing that any of these kids did anything violent. And to think that unsophisticated kids like this could get their ***** together enough to dispose of a body, to not be seen on NUMEROUS surveillance cameras, and for that body to be so well hidden that no one has discovered it.... it all sounds so difficult to imagine.
But I do believe that at the very least, JW knows something or was involved, if it wasn't a stranger abduction. I think, given that JR and JW are buddies, we would have seen fireworks between them if JW believed that JR had something to do with this and was not involved himself. (like the stroy about his confrontation with CR)
As far as a stranger goes, my thinking is that LS could have collapsed and passed out, and it would have been easy pickings to scoop her up off the street. And not even look guilty doing so.
And that 3:38 Bar Manager eyewitness testimony makes me very uncomfortable since it doesn't fit the nice little time line package we have been given.
